The M4/3 field of view varies depending whether you use jpeg or RAW so further complicates the issue. Many RAW converters can deliver right out to the edge where the default jpeg trims a bit, can be significant with some cameras and particularly with wide angle lenses.

Anyway, I think it's way past the time where any M4/3 user should be still thinking in archaic 35mm film terms, I know that I have moved on and just think in terms of what lens I have on the Pen at the time. (9mm really wide, 14mm wide enough for most things etc etc).
